Patented Aug. 11, 1931 UNITED STATES PATENT OFFICE WILLIAM E. H. BELL, 0F GLENSIDE, PENNSYLVANIA, ASSIGNOR, BY ASSIGN- MENTS, TO H. W. BUTTERWORTH & SONS COMPANY, A CORPORATION OF PENN- SYLVANIA DYEING MACHINE CONSTRUCTION Application filed February 14, 1924. Serial No. 692,729.

This invention relates to improvements in dyeing apparatus and deals more especially with an improved form of sheet metal tank or drum construction.

6 It is an object of the invention to improve and perfect an apparatus of the class mentioned so as to reduce liability to tearing or other injury to the goods under treatment, or to staining or discoloration thereof.

A further object of the invention is the provision of a simplified rigid drum construction for an apparatus of the class mentioned having compartments presenting smooth and unobstructed inner surfaces so as to avoid 16 damage to the goods under treatment and resulting in economics in production and maintenance.

A further object is the provision ofa receiver or receiving drum for apparatus of the 2 class mentioned in which interior frame members or other inner projecting parts are entirely avoided.

Other objects will be in part pointed out in connection with the following detailed de- 25 scription of a preferred embodiment of the invention and will be in part obvious in connection therewith:

The invention accordingly comprises the features of construction, combinations of ele- 80 ments, and arrangement of parts, which will be exemplified in the construction hereinafter set forth and the scope of the application of which will be indicated in the claims.

For a complete understanding of the nature and objects of the invention reference is had to the following specification with accompanying drawings showing an illustrative but preferred embodiment of the invention and in which,

Figure 1 is a fragmentary vertical longitudinal section of a dyeing apparatus constructed in accordance with the invention, parts also being shown in elevation;

Fig. 2 is an end elevation of the receiver or receiving drum;

Fig.3 is a detailed enlarged section on line o3-3ofFig.2; t a Fig. 4 is a fragmentary enlarged elevation showing a detail of the enclosing plate connections of the drum; and

14 are fitted and secured against the inner faces of the end frames .bein preferably formed at their upper'edges wit out-turned flanges 15 overlying the upper flanged members 16 of the end frames. The bottom and side plates 13 are provided with marginal outwardly turned end flanges 17 secured to the adjacent extending edges of the end plates, preferably by welding these two adjacent parts together, so as to form a moisture (proof joint. The end frames may be secure to the plates forming the walls by means of bolts 18 extendin through the ext'ernal flanges, and stay r s 18a preferably connect the opposed end frames, lying externally of the tank. A cover plate 19 overlies the top of the tank and may be appropriately hinged or otherwise secured thereto. A pipe or nozzle 20 may be employed being positioned at the bottom of the tank and havmg connections leading through the end wall thereof for the introduction of a heating fluid such as steam, or for admitting the dyeing fluid, and a drain outlet is provided in the bottom of the tank as indicated at 21.

A receiving drum 22 is rotatably mounted 1n bearings 23, 24 secured'to the respective end frames of the tank, the former providing' a bearing for a drive shaft 25 and the latter being open at the top to permit removal of the drum. Trunnion plates ,26 are socured to the ends of the "drum, one having a non-circular aperture for the reception of the correspondin ly'shaped end-of the driving shaft 25, whic also forms a supporting trunnion for this end of the drum. The opposite end of the drum is supported by a trunnion 27 seated in the trunnion plate and resting in the bearing 24.

.The drum is preferably made entirely of sheet metal, monel metal, or other rustproof and acid-proof material being preferred. As shown, the ends are made up of two semi-circular plates 28 and the side walls are made up of a plurality of plates 29 and 30, but it will be understood that any desired number and shape of plates may be employed for making up both the end walls and side walls. Doors 31 are provided for closing the openings leading to the interior of the drum, being preferably hinged in position and provided with latching mechanism as indicated at 32. An interior partition 33 traverses the drum dividing the interior into compartments for the reception of goods under treatment, being secured tothe drum at its edges. It will be understood that more than one such partition may be employed if desired, thus dividing the interior compartment of the drum into three or more separate compartments so goods of different quality or character can be kept separate. One door 31 opens into each compartment.

As shown, the end plates are outwardly flanged as at 34 and the adjacent edges of the side plates 29 and are also similarly outwardly flanged as at 35, the edges of the partition lying between these out-turned flanges and the whole being rigidly secured together as by riveting or welding. In case the partition is omitted, the flanges will be secured directly together. The end plates are also outwardly flanged perimetrically as at 36 and the ends of the side plates overlap and are secured to these outwardly turned flanges.

In some cases it is desirable to enclose the outwardly turned flanges b a smoothly bent plate so as to present a finis ed smooth external joint. Such an enclosing plate is provided by the channel member 37 shown in Figs. 2 and 4, having its flanges secured by rivets extending therethrou h and through the out-turned flanges of t e drum lates. To accomplish the same purpose in a similar manner one of the flanges as 35 may be extended and bent over the adjacent edges of the plates and the-free edge thereof secured by riveting.

It will be observed that the outer edges of the partition plate both at the ends and side walls of the receiver drum lie between and overlap the respective out-turned flanges. Also these outer edges are preferably substantially co-term'inous with the outer edges of said out-turned flanges. The riveting, such as shown, or other rigid securing means, unite these overlapping parts .into rigid, unitary members. When arranged in this manner, substantial structural rigidifying members are provided, reinforcing the end and side walls of the drum and bracing and stiffem'ng the drum structure as a whole.

The trunnion plates 26 are preferably in the form of castings extending across the end of the reel being secured by end flanges 38 to the perimetrical rib, formed by attachment of the flanges 36 with the overlapping edges of the side plates. It may also be secured to a transverse rib or stiflening member through a channel formed in the hub 39. The walls of the drum are provided with the necessary apertures 40 so as to permit circulation of the dyeing fluid.

From the foregoing it will be observed that the drum compartments present entirely smooth and unobstructed inner surfaces there being no obstructing framing members, rivet heads or other projecting parts upon which the goods may catch. Tearing, pulling of threads, and similar injuries to the goods, are thus entirely avoided, which is an important matter especially where sheer goods such as light silks or cottons are under treatment. I11 order to avoid injury to goods where interior frame members are employed as heretofore, not only is it necessary initially to provide perfectly smooth surfaces for such members but they are very prone to become roughened due to rusting or to chemical action of the dyeing material. Also where there are interior metallic frame members of cast metal or the like, chemical action of certain dyes thereon oftenresults in staining and discoloration of the goods under treatment. These difliculties are ontirely avoided by the construction described.

Also it will be noted. that the cooperating secured out-turned flanges and extending edges of the wall plates provide rigidifying or sustaining members for the drum. In this manner longitudinal transverse and erimetrical rigidifying members are provided for the drum forming in effect an external sustaining frame therefor. The partition plate 33 aids in reinforcing the transverse end members and longitudinal side members and supports and rigidifys the drum as a whole. The side ribs or reinforcing members are further reinforced by the channel member 37. So thoroughly is the drum reinforced by this method that it is seldom found necessary to employ other reinforcing means.

Since certain changes may be made in the above construction and different embodiments of the invention could be made without departing from the scope thereof, it is intended that all matter contained in the above description or shown in the accompanying drawing shall be interpreted as illustrative and not in a limitin sense.

It is also to be un erstood that the following claims are intended to cover all Oflihe generic and specific features of the invention herein described, and all statements of the scope of the invention which, as a matter of language, might be said to fall therebetween.
